Guaranteed Minimum Pension
The Guaranteed Minimum Pension (GMP) is the minimum pension which a United Kingdom occupational pension scheme has to provide for those employees who were contracted out of the State Earnings-Related Pension Scheme (SERPS) between 6 April 1978 and 5 April 1997. The amount is said to be 'broadly equivalent' to the amount the member would have received had they not been contracted out.
